  • Publication number: 20120106813
    Abstract: The invention relates to a method for characterizing a perception of blur by a subject (10) in order to determine a dioptric blur value for an image (C) observed by the subject. The image has a blur generated by the low-pass filtering of the image components in accordance with the respective space frequencies of said image components. An indication of the perception thereof of blur in the image is provided by the subject and is associated with the dioptric blur value. Several images associated with different dioptric blur values are used for defining a dioptric blur threshold value for the subject that corresponds to a blur perception criterion. The invention can be used for adjusting the design of a progressive lens for the subject in accordance with the sensitivity to said visual blur of said object.

  • Publication number: 20120092614
    Abstract: The invention relates to the making of a progressive spectacle lens for customizing the lens based on the blur perception by a future lens wearer. Accordingly, a blur threshold value is determined for the wearer according to a blur perception criterion that varies based on an optical-power addition value prescribed for the wearer. The blur threshold value is associated with a reference sight direction for the lens provided to the wearer.

  • Publication number: 20120038889
    Abstract: A method for producing an ophthalmic spectacle lens makes it possible to fit out a wearer of lenses in a manner which is customized as a function of a perception of blur by said wearer. The lens (V4) is selected so that the wearer has the impression of having a field of sharp vision which has a reference width. This reference width is determined on the basis of a first lens (V7) which complies with the wearer's ophthalmic prescription and a reference threshold value of the blur (BR). It is thereafter associated within the lens which is provided for the wearer with a threshold value (B0) of the blur which is perceived by this wearer.

  • Publication number: 20120038630
    Abstract: A method for measuring the perception of spatial orientation of a person comprising the steps of: modifying a first non visual frame of reference and providing a second non visual frame of reference and measuring the value of the parameter representative of the perception of spatial orientation; modifying a first visual frame of reference so as to provide a second visual frame of reference and measuring the value of the parameter representative of the perception of spatial orientation; combining the measured values of the parameters representative of the perception of spatial orientation of preceding steps so as to obtain a value representing the sensitivity of the person referred to a scale of sensitivity to perception of spatial orientation.

  • Publication number: 20120019776
    Abstract: A method for providing a spectacle ophthalmic lens to a wearer, the method comprising the following steps: providing a value, SV, representing the sensitivity of the wearer referred to a scale of sensitivity to perception of spatial orientation, according to both visual and non visual frames of reference; calculating a design of the spectacle ophthalmic lens or selecting a design in a spectacle ophthalmic lens design data base by adapting the management of residual astigmatism and/or optical power repartition according to gaze direction based on the value, SV, representing the sensitivity of the wearer referred to a scale of sensitivity to perception of spatial orientation.

  • Patent number: 8096656
    Abstract: The invention relates to an ophtalmic lens comprising, on its surface, a first central zone preferentially transmitting the long wavelengths of the visible spectrum, and a second peripheral zone preferentially transmitting the short wavelengths of the visible spectrum.

  • Patent number: 8061838
    Abstract: A progressive lens for ophthalmic spectacles has an additional zone for intermediate vision. This additional zone is located beneath a near-vision zone. It enables objects located at a distance of between 1.0 and 1.5 meters, in a direction inclined at about 35 degrees to a line of sight passing through a cross mark (CM) on the lens, to be seen clearly. To achieve this, the optical power progression between a far-vision point (FV) and a near-vision point (NV) of said lens has a power-increase threshold which is located approximately at the cross mark.

  • Publication number: 20110141434
    Abstract: The present invention relates to an ophthalmic lens comprising, on its surface, a first central yellow zone preferentially absorbing the blue light of the visible spectrum, a second peripheral zone preferentially absorbing light having wavelengths of less than 600 nm, and preferentially a third zone which is colourless, grey, or brown in the lower part of the lens.

  • Publication number: 20110128496
    Abstract: A method makes a customised progressive ophthalmic lens intended for an identified wearer that includes measurements of the inclination of the wearer's head. These measures are made when the wearer performs visual tasks in far-vision conditions, by consecutively looking horizontally, then towards the ground. A variation of the optical power of the progressive lens, below a reference direction for the far vision, is adjusted on the basis of the measure results. The habituation period of the wearer to the progressive lens can thus be reduced.

  • Patent number: 7656581
    Abstract: The invention concerns a transparent and polarizing viewing element (2) divided into several zones (2a, 2b). At least one of the zones (2a) is associated with a light polarizing filter. The light passing through the optical surface is affected differently for two of said zones (2a, 2b) depending on the polarizing direction of said light. The polarizing filter is obliquely oriented relative to a horizontal direction (H) in the operational position of the element (2; 5), with an angle between the filter orientation and said horizontal direction of 90 degrees and of 0 degree.
